I obtained the "Cylinder Head Assembly Specifications" for a BMW 325 that is
leaking oil through the head gasket.
Step#1 - 22 ft-lb
Step #2 - Torque angle 90 degrees
Step #3 - Torque angle 90 degrees
The proper tightening sequence is also provided.
I have 3 questions:
Q.1. - Since these specs are for assembly, it would mean (I guess) that a
new gasket is being used. And this might mean that the specs are not really
applicable to my situation since the gasket I have has been in service for a
long time. Or it might be that these specs only apply to a situation where
the head is completely dissassembled. Does anyone know?????????
Q.2. - I would guess that what the specs say is that every head bolt is
tightend in the proper sequence to 22 ft-lb, then 2 more sequences are
performed where a quarter turn is applied to each bolt. Is that what the
specs are saying????????
Q.3. Heck- what if I just tighten the bolts uniformly in the proper
sequence in an effort to stop the leak???????? Would there be any great
harm in that?????
Thanks in advacne.
All responses are appreciated.
